analysis, assesment and principal component analysis of heavy metals in drinking waters of industrialized region of turkey

since they may expose to inorganic pollutants, drinking waters should be investigated andmonitored in industrialized regions. in this study, drinking water samples taken from eight different locationsin heavily industrialized region of turkey, namely marmara region, were analyzed to determine heavy metaland harmful trace element (fe, co, cd, hg, pb, zn, sb, cu, ba, mo, cr, mn and v) concentrations. besidesanalytical analysis, principal component analysis (pca) technique, spatial relationships related to thesemetal elements were also examined. inductively coupled plasma-mass spectrometer (icp-ms) was used todetermine the metal concentrations. the average concentrations in ìgl-1 were as follows: hg. cd and co bdl;pb 0.18 ; zn 27.32 ; sb 0.04 ; cu 6.35 ; mn 2.15 ; cr 1.07 ; v 1.86 ; mo 0.52 ; ba 35.22 ; sr 252. the obtainedresults indicated that the heavy metals concentrations in drinking water samples did not exceed the limitsvalues declared in the guidelines of who (world health organization), epa (environment protection agency)and tse-266 (turkish national standards). however, some v and cu concentrations found to be very closeto tolerable limits declared by epa.
